Audiovisual heritage is by nature fragile. UNESCO, in partnership with the Coordinating Council of Audiovisual Archive Associations, and heritage bodies around the world, has taken a leading role to preserve and share these ephemeral documents.

音像遗产从本质上说是脆弱易损的。为此，教科文组织与音像档案协会协调理事会以及世界各地的遗产机构开展合作，发挥了主导作用，保护和共享这些寿命短暂的人类文献。

UNESCO’s Memory of the World Programme was launched to safeguard valuable documentary heritage and to raise awareness about its inestimable value for present and future generations. The Memory of the World Register, established in 1997, contains close to 200 examples of documentary heritage, including audiovisual, deemed of universal value.

教科文组织发起《世界记忆计划》就是为了保护这些宝贵的文献遗产，提高当代人和后代人对文献遗产难以估量的价值的认识。1997 年建立的《世界遗产名录》收录了近200 项文献遗产的样本，包括被认为具有普遍价值的音像遗产。

To safeguard the world’s audiovisual heritage is to preserve our collective memory, and to ensure its transmission to future generations. We must understand the past to shape a common future founded on dialogue and understanding. On this Fourth World Day, I invite Member States, National Commissions, non-governmental organizations and public and private institutions to promote public awareness and recognition of the significance of the audiovisual heritage and to support efforts to preserve it as a testimony to future generations.

保护世界音像遗产就是保护我们的集体记忆，以确保当代人与后代人之间的传承。只有了解历史，我们才能在对话和理解的基础上，构建我们共同的未来。值此第四个世界音像遗产日，我请会员国、各国全委会、非政府组织、公共和私营机构努力提高公众的觉悟，认识音像遗产的重要意义，协助保存音像遗产，并将其作为历史的见证传递给后代人。
